DETAILED DESCRIPTION

The present systems and methods allow for a visual indication that acosmetic tool, e.g., sponge, may be ready to be used and/or ready to bestored, where the cosmetic sponge may be configured to indicate suchinformation based on certain conditions. Cosmetic sponges increase insize when exposed to water prior to use. The cosmetic sponge disclosedherein may include a thermochromic pigment or dye such that the cosmeticsponge changes color when it is ready to be used and/or ready to store.The change in color provides a visual indicator and/or communication tothe user that the cosmetic sponge has changed modes, where in oneexample, they may begin using the cosmetic sponge or that the cosmeticsponge may be ready to be stored. The thermochromic pigment or dye maybe used to color all, or a part of, the cosmetic sponge. Thermochromicpigment may use liquid crystals and/or leuco dyes depending on theneeded results. In one embodiment, liquid crystals are used in precisionapplications, as their responses can be engineered to accuratetemperatures, but their color range is limited by their principle ofoperation. In some embodiments, leuco dyes may provide for switchingbetween two chemical forms; one of which may be colorless. In oneembodiment, reversible transformations with leuco dyes may be caused byheat, light or pH. Leuco dyes may be used to allow a wider range ofcolors to be used, but their response temperatures may not be set withaccuracy. In other embodiments, the cosmetic sponge may include acombination of liquid crystals and/or leuco dyes since some liquidcrystals are capable of displaying different colors at differenttemperatures. This change is dependent on selective reflection ofcertain wavelengths by the crystallic structure of the material, as thematerial changes between the low-temperature crystallic phases, throughanisotropic chiral or twisted nematic phase, to the high-temperatureisotropic liquid phase.

In one embodiment of the cosmetic tool, the cosmetic sponge may beshaped in a way so as to provide ease of use and ability to hold andapply makeup. Accordingly, the sponge may be in the shape of athree-dimensional folium or a teardrop shape which may look like an ovalwith one end pointed outward. The cosmetic sponge may be completelyconvex, or the cosmetic sponge may become concave as the cosmetic spongenears the point or tip. A completely convex teardrop shape may be calleda folium. That is, the sponge may be shaped to fit all contours of theface. The cosmetic sponge may be made of absorbent material so as toretain liquid, such as water, and result in a change in the size of thecosmetic sponge in addition to the change in color. In one embodiment,the increase in size when exposed to water as well as the change incolor can alert the user that the cosmetic sponge is ready to be used,e.g., damp enough to apply makeup to the skin. In another embodiment,the decrease in size when dry, as well as the change in color can alertthe user that the cosmetic sponge is ready to be stored away.

FIG. 1A depicts a dry cosmetic sponge 100, according to the presentembodiments. The cosmetic sponge may have a general teardrop shape asshown, an oval shape, or a shape with any number of contours. Thevarious angles of the cosmetic sponge 100 are configured to allow thecosmetic sponge 100 to be used on various portions of a user's skin. Thevarious angles of the cosmetic sponge 100 may also make the cosmeticsponge 100 susceptible to rolling on a flat surface, such as acountertop. The material of the cosmetic sponge 100 may also make thecosmetic sponge 100 susceptible to damage if stored with other objects,such as in a purse, handbag, or makeup container.

The cosmetic sponge 100 may include a tip portion 102. In someembodiments, the tip portion 102 may form a point. In other embodiments,the tip portion 102 may be rounded. The tip portion 102 may besurrounded by an angled portion 104. The angled portion may extend froma bulbous portion 106 to the tip portion 102 of the cosmetic sponge 100.The angled portion 104 may include a substantially flat section having aslight curve. The angled portion 104 provides an increased surface areafor contact with a skin of a user when applying makeup, foundation, orthe like from the cosmetic sponge 100. The tip portion 102 allows forfine application of makeup, foundation, or the like. For example, thetip portion 102 may be used for areas around the eyes of a user. Thebottom portion 108 may be surrounded by the bulbous portion 106. Thebulbous portion 106 may be disposed proximate the bottom of the cosmeticsponge 100 so as to provide additional surface area for the angledportion 104 and the tip portion 102 when applying makeup, foundation, orthe like. A user may grip the cosmetic sponge 100 proximate the bulbousportion 106, which allows the user to bounce the cosmetic sponge 100against the skin while maintaining a secure grip on the cosmetic sponge100. The bottom portion 108 may be used for applying and/or blendingmakeup, foundation, or the like on larger areas of the skin, such ascheeks, the neck, or the like. The cosmetic sponge 100 may have symmetrysuch that the cosmetic sponge 100 may be used without needing to orientthe cosmetic sponge 100 in a particular direction. Accordingly, thecosmetic sponge 100 may be picked up and used by a user by feel wherethe user can adjust their grip by touch to apply makeup, foundation, orthe like via the tip section 102, angled section 104, bulbous section106, and/or bottom section 108.

FIG. 1B depicts a dampened cosmetic sponge 110, according to oneembodiment. The cosmetic sponge (100, FIG. 1A) may be dampened, such aswith water, prior to use. In another embodiment, the cosmetic sponge(100, FIG. 1A) may be dampened with a cleaning solution. Adding water tothe cosmetic sponge (100, FIG. 1A) causes the dampened cosmetic sponge110 to increase greatly in size. The dampened cosmetic sponge provides agreater surface area and absorption for applying makeup, foundation, orthe like. Once the dampened cosmetic sponge 110 has been used for theintended purpose, the cosmetic sponge 100 may remain at the larger sizefor several hours before drying and returning to its original size. As aresult, the dampened cosmetic sponge 110 may not fit in an originalpackaging or space the cosmetic sponge 100 fit prior to use. Squishingthe dampened cosmetic sponge 110 to fit in an original packaging orspace may cause damage to the dampened cosmetic sponge 110 and/or reducethe lifetime of the dampened cosmetic sponge 110. Due to increased sizeof the cosmetic sponge, the dampened cosmetic sponge 110 is moredifficult to store and more susceptible to rolling on a flat surfacethan the dry cosmetic sponge (100, FIG. 1A).

FIG. 2A depicts a dry cosmetic sponge 200 having a first color 206,according to one embodiment. In some embodiments, the first color 206may be purple. The first color 206 may be via a thermochromic pigment ordye. The dry cosmetic sponge 200 may be smaller in size as the drycosmetic sponge 200 is not saturated with water, such as from a faucet208. The cosmetic sponge 200 via the thermochromic pigment or dye, maychange colors based on a change in temperature, in some embodiments.

FIGS. 2B-2C depict the cosmetic sponge 200 of FIG. 2A changing color asit absorbs water 210, according to one embodiment. The cosmetic sponge200 may in some embodiments increase in size as it absorbs liquid, suchas water 210 from, for example, the faucet 208. In one embodiment, thewater 210 is lukewarm water from a faucet. In another embodiment, thewater 210 is cold water from a faucet. In another embodiment, the water210 is hot water from a faucet. The cosmetic sponge may begin to changecolor from the first color (206, FIG. 2A) to a first transition color212 and to a second transition color 214 as the cosmetic sponge absorbsliquid over a period of time. In some embodiments, the first transitioncolor 212 and/or second transition color 214 may be a gradient of colorsfrom the first color (206, FIG. 2A) to the second color (216, FIG. 2D).For example, if the first color (206, FIG. 2A) is purple and the secondcolor (216, FIG. 2D) is white, then the transition colors 212, 214 maybe increasingly fainter shades of purple.

In one embodiment, the cosmetic sponge 200 may change color in responseto temperature, such as temperature of the skin. For example, thecosmetic sponge 200 may change color at the areas where the cosmeticsponge 200 is being gripped by a user's finger tips. In another example,the color of the cosmetic sponge 200 may change based on the location ofthe face that the cosmetic sponge is being applied. For example, theforehead may be warmer than the cheek; hence, the forehead my cause thecosmetic sponge 200 to be a different color or shade than when thecosmetic sponge 200 is applied to the cheek.

In another embodiment, a certain change in color of the cosmetic sponge200 may be an indication that the cosmetic sponge 200 is being usedincorrectly. For example, dabbing of the cosmetic sponge 200 on the skinmay be the correct motion for optimal application of a certain makeup.In this case the cosmetic sponge 200 may turn blue when being applied inthis correct manner. However, if the makeup is applied in an incorrectfashion, such as dragging of the makeup with the cosmetic sponge 200across the skin, the cosmetic sponge 200 may transition to a red color.Other possible color combinations are possible and contemplated.

FIG. 2D depicts the cosmetic sponge 200 of FIGS. 2A-2C having the secondcolor 216 after absorbing water, according to one embodiment. The secondcolor 216 may be lighter so as to better show any makeup, foundation, orthe like that are applied to the surface of the cosmetic sponge 200. Insome embodiments, the second color 216 may be white. The first color(206, FIG. 2A) may be a darker color, such as purple, so as to hide anydiscoloration from makeup, foundation, or the like.

In one embodiment, the cosmetic sponge 200 may change color based on thespecific makeup or type of makeup being applied. More specifically, thecosmetic sponge 200 may change color in a particular area indicatingthat the particular area is most suited to be used for applying thedesired cosmetics, based on the specific or type of makeup applied. Thatis, in one example, a tip portion of the cosmetic sponge 200 (see forexample tip portion 102 of FIG. 1A) may change color indicating that theparticular area of the sponge should be used as this area may be mostsuited to apply eye makeup in the areas close around the eye. In anotherexample, a bottom portion of the cosmetic sponge 200 may change colorbased on a particular cosmetic that is applied to the sponge.Accordingly, a particular cosmetic may be applied to the entire spongeand based on the type of cosmetic, the sponge may determine which areato change color so as to indicate to the user which areas are best to beused with that particular cosmetic, where the determination may, in someembodiments, be based on the chemical formula of the particularcosmetic. In one embodiment, to accomplish different areas of thecosmetic sponge 200 turning a different color, the cosmetic sponge 200may be made of different materials in different areas of the sponge. Forexample, the cosmetic sponge may comprise one or more divisions and/orsubdivisions where each subdivided area on the sponge—depending onnecessary usage—may comprise material that turns a specific color basedon a specific liquid temperature and/or chemical formula of thecosmetic. Any combination of material and/or subdivisions iscontemplated as part of these embodiments. In one embodiment, the one ormore subdivisions may be a bulbous end of the cosmetic sponge 200, thetip of the cosmetic sponge 200, and so forth.

In an alternate embodiment, the user may use a particular temperatureliquid based on the type of cosmetic they want to use and the cosmeticsponge 200 may change color in a specific area which is most appropriatefor use for that cosmetic. That is, based on a predefined mapping, theuser may use cold, lukewarm, warm, hot, etc. liquid such as water, andthe cosmetic sponge 200 change colors at the tip signaling that for thatparticular type of makeup, the best use would be to apply the cosmetic.

In another embodiment, the first color 206 of the cosmetic sponge 200may change to a second color 216, different than the first color,depending on the type of cosmetic being applied to it, for example,whether a foundation is being applied versus a concealer. In oneexample, the cosmetic sponge 200 may change to a second color 216 red iffoundation is being applied to the sponge, while the cosmetic sponge 200may change to a second color 216 blue if concealer is being used.Accordingly, the sponge, by changing color based on the different typeof cosmetic being applied to the sponge, may indicate to the userwhether they are using the correct cosmetic for their purpose.

In one embodiment, only a portion of the cosmetic sponge 200 may changefrom a first color 206 to a second color 216. For example, the cosmeticsponge 200 color may change in an area that corresponds to a preferreduse of the cosmetic sponge 200, such as a tip portion changing color toindicate the cosmetic sponge 200 is to be used for eye makeupapplication. In another embodiment, the cosmetic sponge 200 color maychange in an area that indicates where to grip the cosmetic sponge 200for optimal application. For example, for application of eye makeup witha tip portion of the cosmetic sponge 200, the cosmetic sponge 200 maychange color at the bulbous bottom section of the cosmetic sponge 200 toindicate to the user to grip the cosmetic sponge 200 at the bulbousbottom section.
